DAMPER CONTROL Y Lynt White, Reginald Hutchins Hodgson, Robert HenryWhite, and Bolling` H. Jones, Jr., Atlanta,` Ga., assignors to TheAtlanta Stove Works,

UNITED STATES PATal'vrf,jA OFFICE Inc., atlanta, Ga., a corporation ofGeorgia'` Application June 5, 1939,'s'eri1 No,` 2:11500 3 claims. l (c1.126-1) The invention relates to control of the dampers of a stove andhas as an ob-ject the provision of convenient means extending to thefront of the stove to control the draft damper and the ue damper. I

It is a, further object of the invention to provide such damper controlso located as to be not heated while the stove is in operation wherebythe manually actuated control means will not be too hot to be handled bythe bare hand.

It is a further object of the invention to extend the controls toconvenient points for operation.

Further objects of the invention will appear from the followingdescription when read in connection with the accompanying drawingsshowing an illustrative embodiment of the in` vention, and wherein:

Figure l is a. perspective View of a stove indicating the controlextensions and dampers in dotted lines;

Fig. 2 is a detail vertical section on line 2-2 of Figure 3 showing theoven damper;

Fig. 3 is a detail side elevation of the structure of Figure 1 as seenfrom the right of said figure;

Fig. 4 is a detail end elevation of the structure of Figure 1 as seenfrom the left of said figure; and

Fig. 5 is a detail vertical section on line 5-5 of Figure 4.

The full details of the structure of the stove are not shown as thestove itself is of conventional form. As is common with stoves, there isa damper the opening or closing of which causes the heat to passdirectly from the firebox to the flue with a minimum of heating effectupon the oven, or to pass over, around and below the oven upon itscourse to the flue whereby the oven is heated.

In the structure shown this damper comprises a sliding plate Ill havingopenings I I therein, the plate being slidable to cause said openings IIto be in or out of registry with openings I2, leading directly to theflue I3, to which the stove-pipe is connected.

To control the sliding of this damper, in accordance with the presentinvention, the plate I I is shown with an arm I4 leading across the backof the stove and extending through a slot I5 andthe end wall thereof.The end of the arm I5 where it projects to the exterior of the stove isshown as provided with a down-turned portion I6 formed with a slot Il.

A bell crank comprising a fulcrum rod I8 ex- 55 tends across the stoveunder the projection I9 thereof and inside of the outer flange 20 whichextends around the stove top. Desrably a lug 2I is cast between the ange20 and the outer end wall 22 of the stove, which lug may be integralwith the stove top and with the ange 28, and which contains an openingto serve as a bearing for the fulcrum rod I8.

The fulcrum rod I8 is formed with a downwardly extending arm 23 of thebell crank and terminates in a projection 24 working in the slot I1.across the end of the stove through the portion 24 of the flange 20 andterminates in a head 25 to be grasped for the purpose of causingrotation of the fulcrum rod I8 and consequent sliding of the damper IU.

For control of the draft damper 26, which is shown as swingable aboutpintles 21, 28, engaged in lugs 29, 30, carried by the end wall of thestove, the said damper 26 is shown as provided with an extension 3|having a portion 32 formed with an elongated slot 33 for engagement by aprojection 34carried by an arm 35 of a bell crank formed of the arm andof a fulcrum rod 36 extending across the width of the stove andterminating in a head 3l at the iront of the stove by which revolutionof the fulcrum rod 36, swinging of the arm 35, and consequentmanipulation of the damper 26 may be produced.

It will be seen that the fulcrum rods I8 and 3G are concealed from viewby the flange 20 and yet are not within the heat zone of the stove andthat therefore the manipulation of the dampers may be carried out by thebare hand while the stove is in use. The manipulation is convenient tothe hand of a person working at the front of the stove and thearrangement presents a pleasing appearance. The fulcrum rods act bybeing revolved as compared with lengthwise sliding movement and hencewill not in any position project to be in the way of a person working atthe stove.

Minor changes may be made in the physical embodiment of the inventionwithin the scope of the appended claims without departing from thespirit of the invention.

We claim:

l. Stove damper control comprising, in combination: a stove having a topprovided with a down-turned ange; a damper having a portion exposed atthe exterior of the stove and provided with an elongated slot; a rodconcealed beneath the downturned ange of the stove top; a bell crankextending from said rod and having The fulcrurn rod I8 as shown extendsa portion engaging said slot; said rod extending from said bell crankarm to the front of the stove and journaled in an opening in the frontflange of the stove top; and a manually operable member secured uponsaid rod at the front exterior of said ange.

2. Stove damper control comprising, in combination: a stove having a,top provided with a depending ange'; a damperV having a portion exposedat the exterior of the stove; a bell crank comprising a rod journalledin the space belowvk the depending flange of the stove top, extending Ialong an end of the stove in said space and penetrating the portion ofsaid flange at the front'of* the stove; a. hand piece yon said. frontextending portion for manipulation of the. damper'by the l rod; and anarm of said bellv crank projecting downwardly from said rodand.engagingsaid` exposed damper portion for operation of` the damper byswinging of said arm.

V*the end of the stove and extending to the front thereof and a manuallyoperable crank member y 'exposed at the front of the stove, formanipulation of the damper.
